Application filed January 2, 1909.

' b all whom it may concern:

Be it known that I, JaMEs HAMILTON, a citizen of the United States,residing at Grand Junction, county of Mesa, and State of Colorado, haveinvented certain new and useful Improvements in Orchard-Heating Devices;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled 0 inthe art to which it appertains' to make and use the same, referencebeing had tothe accompanying drawings, and to the figures of referencemarked thereon, which form a part of this specification.

5 My invention .relatesto improvements in orchard devices, my object beng to rovide an article of this characterjwhichs all be well adapted foruse in raising the'temperature sufficiently in the vicinityl'o'forchards, to gardens and in all localities containin vegetation, toprevent injury thereto by rost.

My improved'device comprises a receptacle for liquid fuel, as'oil, inwhich is located j ;requ1red,- itf s often impossible to obtain anadjustable partition or'bulk head, whe re by the receptacle maybedivided into two compartments having any desired relation to each otheras regards volume or capacity.

t On one side of the partition the liquid fuel is lighted and this comartment forms a combustion chamber; while on the opposite side theliquid fuel constitutes a source of supply for the combustion comartment. While the partition fits quite close y within (the receptacle,the oil will pass between its adjacent edges and the walls of thereceptacle and maintain the liquid fuel at the same level in bothcompartments.

My improved device is exceedingly advanta eons for the purpose stated,from the fact that by simply ad usting the partition separating the twocompartments, an increase in heat from each individual device may beobtained, since by the movement of the partition the size of thecombustion chamber or compartment is enlar ed, exosing an increasedsurface area of t e burnmg liquid. It is evident that the fuelreceptacle may be made of any desired size whereby a suflicientquantityof oil may be placed therein to last an entire season.

adjustment of the partition a small quantity of liquid fuel may be exosed, or a considerable'quantity, as desire while with other devices itended for use in heating orchards, so far as -m aware,"'in order toincrease the Specification of Letters Patent.

heating capacity it is necessary to add additional heating devices,since each device is a unit, and its heating capacity cannot beincreased. This is believed to be true so far as all devices of thischaracter for the bunk--61) ing of liquid fuel are concerned.

he facility with which my device may be regulated for the purpose orincreasing the heat, is exceedingly important, since it often .happensthat there is a sudden fall oftem- 5 perature, and under ordinarycircumstdn ces, or where other heaters are used, there would not besufficient time to place additional heaters in the orchards until thedamage had resulted; while with my device a single individual canquickly adjust the partition of a great manyof; these devices, and thusimmediately increase the fire or heating ca- ;pacity of each device.'This'is' also very important for the reason that during the period whendevices of this character are needed, it is usually difiicult to obtainworkmen, and where :a considerable number are them. With my device nodifliculty of this so kind can arise, for the reason heretofore stated.

'Having briefly outlined my im roved device, I will proceed to describet e same in detail, reference being made to the accomas,

panying drawing in whichis illustrated an embodiment thereof.

In this drawing, Figure 1 is a perspective view of my improved orchardheater. Fig. 2 is a. vertical longitudinal section of the 9 the coverand partition or bulk head ad]usted for use, the receptacle beingprovided withliquid fuel. Fig. 3 is a cross section of the device takenon the line 3-3 Fig. 2. Fig. 4 is a perspective view in detail of oneform of the partition or bulk head. Fig. 5 is a similar view of anotherform of said partition.

The same reference characters indicate the same parts in all the views.10

'Letthe numeral 5 designate a receptacle ada ted to contain liquid fuel,as oil, which is esignated in Fig.2 bythe numeral 6. This receptacle isprovided nearits top with perforations 7, which preferably extend en- 10tirely around the receptacle, that is to say, on all four sides thereof.As shown in the drawing, one extremity of the receptacle has its sideand end walls formed somewhat higher than the corresponding walls of the1 opposite portion. The part having the higher walls may be designatedthe forward end of the device, or that where the fuel is to be lighted,and which will constitute the combustion chamber. This portion of thedevice is provided with additional perforations 7 formed in the upperportion 8 of the side and end walls. Located within this receptacle isthe partition or bulk head 9, which, if of the form shown in Figs. 2 andt, is preferably formed hollow, as shown at 10, and composed of tireclay, or other material adapted to resist the action of the heat in thecombustion chamber. This partition may be of the construction shown inFig. 5, in which the body part is composed of a metal plate 12 havingside wings 13, an as bestos member 14 being applied thereto to preventthe heat from passing readily from the combustion compartment to thecontents of the receptacle on the opposite side of the partition. Thisasbestos member occupies a position in contact with the metal plate 12and between the side wings 13. It is evident that many different formsof construc tion for this partition may be employed. Any suitable formmay be used that is adapted to prevent the too rapid travel of the heatfrom the combustion chamber to the chamber containing the source of fuelsupply.

It is evident that it is not desirable that the li uid fuel in thereserve chamber should be an uly heated. It will, however, be kept warmor of sutlicient temperature to cause it to flow readily, thus puttin itin proper condition for passing around the partition into the combustionchamber with sutIicient freedom to maintain the level of the fuel thesame in both compartments.

Whichever style of partition is employed it is made to fit the oppositeside walls the receptacle 5, and is readily slidable therein. The sidewalls of this receptacle are preferably inclined, whereby the receptacleis widest at the top and diminishes in width toward the bottom. Byvirtue of this construction, a partition whose opposite edges fitbetween the two side walls will be sure to maintain an n right positionat all times. When formed 0 fire clay, or other similar material, it isimportant that the partition or bulk head should be hollow or rovidedwith an air chamber which is Well a apted to prevent the passage of Heatthrough the partition. It is evident that in choosing material for thisbulk head or partition, those substances possessing a high degree ofheat conductivity should be avolded.

My improved device is further provided with a cover 15, which isslidably mounted between the side walls of the receptacle. The upperedges of these walls are turned inwardly, as shown at 16, to form guideways for this cover, whose forward portion rests when the cover isproperly adjusted. \ttI- isters with the chamber of the hollow bullchead. hen the cover is so adjusted, a tool (not shown), of any suitablecharacter may be inserted in the openin; 18, whereby it is caused toprotrude into the chamber 10,

whereby the cover and bull: head or parti,

tion may be moved back and forth simul taneously.

From the foregoing description, the use of my improved device will bereadily under stood. Any desired number of these devices may be locatedin the orchard or other locality needing protection from frost. Thedevices may be located at such intervals as desired. Each receptacle 5should be sup plied with a quantity of fuel oil. In the first instancethe partition 9 should be adjusted to expose any desired surface area ofthe oil, according to the amount of tire required. If it is only desiredto produce a small quantity of heat, the partition is moved to expose acorresponding surface of the oil, while if a greater fire should berequired, the partition is readily adjusted to expose a greater area ofthe liquid fuel within the combustion chamber, or forward extremity ofthe receptacle. When this is done the oil within the exposed compartmentof the receptacle is lighted, the cover 15 being adjusted so that itsforward extremity shall rest upon the top of the bulk head or partition.

The function of the perforations 7 at the left of the partition is toallow the escape of any gas that may be formed, due to the heating ofthe oil, or liquid fuel, within the compartment at the left of thepartition, refer ring to Figs. 1 and 2. These perforations are thereforeconsidered an element of safety to prevent possible explosion, due tothe formation of gas by heat conducted from the combustion chamber. Theymay be used or not, as desired.

Having thus described my invention, what I claim is:

1. A heating device, for the purpose stated, comprising a receptacle forliqu d fuel, a partition or bulk head located therein dividing thereceptacle into two compartments, the said partition being adjustablymounted in the receptacle and arranged to permit; the'flow of fuel. fromone side of the partition to the other, for the purpose set forth.

2. A device of the class descr1bed,comprising a receptacle for liquidfuel, a partition or bulk head adjustable longitudinally therein andarranged to permit the flow of fuel from one side of the partition tothe other, and a cover slidably mounted on the receptacle, for thepurpose set forth.
